2019-01-18 Thread Paolo Cavallini 
Sorry, I can't confirm. In the images you can see the contour displayed.
IMHO it is a bug, because what is shown on canvas should be also
exported without missing an information.
Would you agree?
Thanks.

Hi Paolo,

For Multiply to work, it seems you need to have a Contour quantity
displayed. Not sure if it is a bug or a feature! :)

Thanks

Hi Paolo,

I can't see Fusion for rendering. I tested it with Addition:

Hi Saber,
thanks for your reply. I did many tests, and to me the picture is clear:
the arrows are always displayed on the canvas. On the other hand, they
are not exported when the Layer rendering is set to Fusion and the
colour is white.
All the best.

Hi Paolo,

Did you try then option for arrows: Display Vectors on User Grid
You can have more arrows by decreasing the values on X and Y spacing (it is
done by interpolating the actual values).

Maybe having more arrows will result in something appearing in the output?

[QGIS-Developer] GRIB: arrows disappear when exporting the canvas

2019-01-17 Thread Paolo Cavallini 
Hi all,
after loading a grib, if I style the arrows in white, with the Layer
rendering: Fusion, the resulting PNG does not display the arrows,
whereas they are displayed correctly in the canvas.
Am I missing something, or this is a bug?
Thanks for comments.
